Ubuntu/Debian NFS and VMware Cloud Director Database backup Permission Denied Issue

Actually i never faced such issue with Centos 7/8 before, after Centos Stream happen generally too many people start to look different OS to use. Ubuntu is one of this ….

Our VMware Cloud Director use NFS for transfer/shared storage and its on Ubuntu. There is no issue about installing cells but have an issue about backup PostgreSQL. Error is permission denied.

Problem is not about rights or any settings. Support informed that “RPC mount point handling in nfs-kernel”

When we start to search find out something about –manage-gids, its about user and that user joined 16 groups and this time some problems happen about NFS Server and NFS Client UID/GID binding.

There is a file in Ubuntu 20.x /etc/default/nfs-kernel-server. there is an option here like RPCMOUNTDOPTS which came default RPCMOUNTDOPTS=”–manage-gids” . Remove –manage-gids and leave the option empty like RPCMOUNTDOPTS=”” and restart NFS server and reboot the vcd cell (also i believe you can remount it but its safe to reboot)

Everything will be fine !
